In The Event Of A Fault In The Parking Brake - Volvo XC90 TWIN ENGINE Owner's Manual

STARTING AND DRIVING
In the event of a fault in the parking
brake
Contact an authorised Volvo workshop if it is not
possible to release or apply the parking brake
after several attempts.
An acoustic warning signal sounds when driving
with the parking brake applied.
If the car must be parked before a possible fault
is rectified, then the wheels must be turned as for
parking on a hill and the gear selector must be in
position P.
Low battery voltage
If the battery voltage is too low then the parking
brake can neither be released nor applied. Con-
nect a donor battery if the battery voltage is too
low.
Replacing the brake linings
The rear brake linings must be replaced at a
workshop due to the design of the electrically-
operated parking brake - an authorised Volvo
workshop is recommended.

Hill start assist
Hill start assist, Hill Start Assist (HSA), prevents
the car from rolling backwards when starting on
an uphill gradient. When reversing uphill, it pre-
vents the car from rolling forwards.
The function means that the pedal pressure in
the brake system remains for several seconds
while the driver's foot is moved from brake pedal
to accelerator pedal.
The temporary braking effect releases after sev-
eral seconds or when the driver accelerates.
Hill start assist is available even if the function for
automatic braking when stationary (Auto hold) is
deactivated.
